I have a problem with the motor, I know that the motor is originally crooked but I have a big problem. So there are about 2 large parts to the motor the part that spins and the part that doesn't spin. the part that doesn't spin is connected to the drone and the part that does spin is the part you can only see from the outside. When my drone takes off after a few minutes my motor makes sounds louder than the props cutting through the air. The outside part is suddenly more crooked than usual and rubs against the inside part that the motor doesn't move at all, so sometimes I can't even get it to fly. Can I fix this myself, or do I have to buy another motor?
